Seeing that Lan Yu didn't care about the quarrel at all, Lan Feng and others all showed helpless expressions. In the end, Lan Huaien stepped forward again and said, "Grandfather, Your Majesty is the co-lord of the world after all. As subjects, it is really a bit more polite to argue with Your Majesty!"

"What kind of courtesy is beyond that? No matter how noble your Majesty is, he will make mistakes. Can't I say it if I am unfair?" Lan Yu said angrily again, not listening to the words of his children and grandchildren at all.

"Don't calm down, it's not that my father won't let you say it, but that Your Majesty is His Majesty after all. Even if you don't think about yourself, you should think about Huai'en and the others. Yun Niang was just worried that your father would anger Your Majesty and cause disaster to destroy the family, so she took Zhen'er back to her parents' home." Lan Feng also took a step forward and persuaded him again with great sincerity.

It was the first time that Lan Yu met his children and grandchildren so bold that he refuted him several times, and said that his granddaughter-in-law took his great-grandson back to his parents' home and blamed him for it. This made him angry for a moment. However, at this moment, a flash of inspiration flashed in his mind and immediately realized something was wrong, because based on his understanding of his children and grandchildren, their performance today was really too abnormal.

Thinking of this, Lan Yu calmed down suddenly. He glanced at Lan Feng, Lan Huai'en and his son with a gloomy face. None of these people dared to look at Lan Yu, and all of them lowered their heads, which made Lan Yu even more sure of his guess.

"Tell me the truth, has anyone told you something?" Lan Yu asked in a deep voice.

When Lan Yu said that, Lan Feng and others all lowered their heads, especially Lan Huai'en, whose head was almost stuffed into their chests. Of course, this method was taught by Li Jie, and he also said that if he was seen through, he would tell the truth, but he was still worried about his grandfather's next anger.

Lan Yu was the general who commanded the Thousand Army. He could see Lan Huai'en's abnormality at a glance, and immediately snorted angrily: "Hui'en, what's going on? Did Zhen'er really be taken back to her parents' home by Yun Niang?"

"Grandfather calmed down, Yun Niang did take Zhen'er back to her parents' home. Grandson would never dare to deceive her grandfather in such a thing!" Lan Huaien replied immediately. In order to make the scene more realistic, he did ask his wife to bring her son back to her parents' home. He did not lie.

"You only answered half of my questions. Has anyone told you what you said?" Lan Yu yelled again angrily.

Now Lan Huaien finally dared not hide it. He hesitated for a moment and finally told the truth: "Report to my grandfather, my son-in-law Li Jie has found me before. Grandfather, the son-in-law told me about your quarrel with Your Majesty."

"I just knew that not many people knew about this. Apart from this kid Li Jie, no one would dare to talk nonsense!" Lan Yu was so angry that she slapped the table again when she heard this. After saying that, she stood up and left.

Lan Huaien was shocked when she saw this, and immediately stepped forward to stop Lan Yu and asked, "Grandfather, where are you going?"

"Where can I go? Of course I'm going to settle the score with this guy Li Jie!" Lan Yu replied angrily, and after that, she walked out.

"Don't calm down, my son-in-law told us this, and it was also good for me!" At this time, Lan Huai'en's father, Lan Feng, also quickly stepped forward to stop him.

"What a good intention, he just wants to provoke the relationship between our family and watch the show next to him!" Lan Yu was so angry that he pushed his grandson aside, and then took big steps away from the Duke of Liang's Mansion.

Lan Huaien, Lan Feng and his son looked at the departure of Lan Yu, and they all looked at each other and smiled bitterly. This situation was not beyond their expectations. After all, they could not understand Lan Yu's bad temper. Even the emperor dared to go and argue, let alone Li Jie.

"Hui'en, did the prince-consort really ask you to tell your grandfather the truth?" Lan Feng asked his son with some uncertainty. He was really worried that his father Lan Yu would go and beat Li Jie up. Maybe Lan Yu was not afraid of Li Jie, but you must know that Li Jie is very young. If Lan Yu is gone, Li Jie can vent their anger.

"It's true, that's what the prince-consort told me, but now I'm worried that my grandfather would run to find the prince-consort so angry. What if the two of them had a conflict?" Lan Huaien said at the end, his face also showed an extremely bitterness. If he offended Li Jie again because of this incident, their Lan family would definitely be very miserable in the future.

"The prince consort is extremely talented. Since he dares to say this, he must have expected this situation. Moreover, he is an important official in the court after all, and his father may not really do anything to him." Lan Feng said at this time.

After hearing his father's analysis, Lan Huaien finally breathed a sigh of relief, of course she was just relieved. After all, they all knew Lan Yu's bad temper, and no one was sure if he would really take action when he saw Li Jie?

At the same time, Li Jie did not wait for Lan Yu at home, but instead took time to come to the Qiuzhen Academy. After so long development of the steam engine, it finally made a major breakthrough.

"Boom~Boom~" A steel giant beast made a smooth roar, resounding throughout most of the academy. Li Jie and Guo Zhenglin stood in front of the steam engine. Looking at the normal-operated steam engine, both of them showed a hint of emotion on their faces.

"Brother Li, the steam engine has been successfully developed. Nanjing has also loaded it on the ship and has been launched. Now it is heading towards Beijing. Although the steam engine on the ship is not as good as ours, it can be barely used." Guo Zhenglin introduced to Li Jie loudly. The sound of the machine is too loud and the voice is too low to be heard.

The steam engine was developed by the north and south hospitals of the Xuzhen Academy. Among them, the branch in Beijing was the first to study, the largest investment, and the developed steam engine also had the best performance.

However, Nanjing is not willing to fall behind. It is now focusing on the application of steam engines, such as the development of steam boats and steam cars, which are better than that of Beijing. Now a steam boat is coming from Nanjing to Beijing. At that time, the steam engines in Beijing will be replaced, making the ship's performance more superior.

"Brother Guo, thank you for your hard work. When the court stabilizes, I will write a letter to suggest building a railway from Beijing to Taijin, and steaming cars will be put on the agenda." Li Jie smiled when he heard this.

"That's great. I have steam boats and steam cars. I can go anywhere in the world in the future!" Guo Zhenglin said ambitiously when he heard this.

Hearing Guo Zhenglin's words, Li Jie also thought of convenient transportation in later generations. Although the transportation conditions in later generations are still countless times different, at least there is a good start.
